Application filed Nove'nibcnlfi, 1926. Serial No. M1577, and in (ierinany' October 14, 1926.

This invention relates to an arrangement, by means of which acovered room, entirely or partly provided with side walls, is instantaneously transformed into a free space, without disturbing its continuous utilization. The invention can be used for most various purposes, as for instance, hotel halls, factories, workshops, amusement halls and the like.

. The spirit of the invention is to be found in the fact, that with most simple means, and Without disturbance of its continuous use,

root and walls of a covered roo1n,as far as be'removed.

wa a d root can b shifted or rolled aside simultaneously and independently the one from by thesubdivision orseparations' of the sow eralf parts can take place atwill. The invention can be applied to most various places and has therefore a: quite special value. The invention has the further great advantage to make serviceableto the public those many grounds, which up to the presentcould not they are provided, can

' be used owing to fire-danger, hygienic reasons, police-regulations" and the. like.

In technical works, in which from time to time great quantities of steam or the like occur, or where, owing to an accident of some kind, poisonous gases occur in great quantity, the whole room can instantaneously. he opened by means of the improvedarrange ment forming the object 01" the present invention, thus avoiding" great accidents and danger. f

The present invention is further advantageous for lay-halls, cure places especially for pulmonics, because. the hall can instantaneously be adjusted to the actual atmospheric conditions. I

Oneform of execution of the object of the present invention is shown,1by wayot example, on the accompanying drawings, in which Fig. 1 is a: frontelevation Of aliall with closed walls and'closed roof. M

Fig. 8 "is a front] elevation of the automatic covering for the guide-channel when the central part of the hall is opened.

The hall shown by way of example in'the accompanying drawings consists'ot the stationary sidewalls A A. of the centre-walls B, B, of the stationary rootportions Q, C, and of the displaceahle roof portions D, D The several parts are arranged insuch a manner, that the ro'of-andwall portions to be displaced in one and the same direction; are made in one p1ece,that means, roof D 1 and frontwall' B respectively D andB consistofa solid rigid frame, so. that, whendisplacing one part of thesubdivided'portions,

portions, there is further provided a roofdrive. The walls B,'B rest with their rollers 0, on guide rail pjfor the roof portions, a roller-guide 0, p (Fig! 3)' is provided.

" The lower chain m (F' g. 7') is guided over of the toothed wheel aides, chain wheels t, t

are". "keyed, which latter engage with rolls in order tofavoid clamping of theuseveral 1 chaiir or toothed wheeljsfs, sand upon each or links a, u of a continuous doublechain,"

onto whichlinks,checqueredor erf rated the right hand side of the hall, and once at thelett hand side thereof, viz, at s, s" (Fig. l). Further'it is to be understood that two continuous checquered-plated double chains are provided (Fig. 8) running the on'eov'er ,toothedidouble wheel Iand chain wheels t, t at theleft hand sideofthehall, and the -sheet-iron"plates"o and the like are fixed (F1g: 8) It is to be ,iiinderstood" that a device as shown in Fig." 7 is mounted once at channel will automatically becovered by the continuous checquered-plated double chains, so as to shut the open guide-channel flush with the earth.

Underneath the roof a subdivided intermediary or auxiliary ceiling is provided, which serves as dustor heat protector. T he ceiling portions F, F lay st'ationarily under the roof portions C, C, whilst the ceiling portions E, E, underneath the displaceable roof portions D, D, can be raised, by means of pulleyand cord arrangements or the like, in order that the portions E, E may, when opening the centre part of the room, be cased beyond the stationary roof portions C, C simultaneously with the displaceable roof-portions D, D. F or this purpose a differential pulley 0 is driven, by means of a convenient hand-drive, or motor, 6, which pulley c rotates the rollers e and f by means of any suitable cord-arrangement.

With the objectshown on the drawings, the intermediary central ceiling portions mustbe brought, prior to being displaced, from theirhorizontal position into an angular position, for which purpose the differential pulley is applied, which pulley pulls the cord. running over roller f, quicker than the cord running over roller e,this in such relation as is necessary for the purpose set forth .(Fig. 6). The intermediary ceiling portions E, E are thus brought-into their correct position previous to their being laterally displaced simultaneously with the roof-portions D, D.

The displacement of walls B, B and roof portions D, D takes place, either by handdrive or by motor a, which motor, by means of a'shaft g, toothed wheels h and shaft h, rotate the chain wheels z, i and s, s, which latter also rotate the continuous chains 70, m. Onto the upper chain A}, the bolts or pins 9 and r are solidly fixed, and onto the lower chain m, bolts or pins 9 and r are solidly fixed, thus securely conducting at top and bottom the portions to be displaced. The driving means for displacing the walls and roof portions are provided at the front bottom part and rear upper part of the hall. The front chain serves only to displace the front Walls, whilst the rear upper chain serves to displace the roof portions simultaneously with the ceiling portions.

The gear-parts Z), 0, e, f. for raising and lowering the ceiling portions E, E arepreferably fixed 'to the bottom surface of the displaceable roof portions (Fig. 6).

The drive for the front walls and for the roof can also, when roof and front walls do not form a rigid whole, be separated by couplings, in such a-manner, that both parts together, or each one for itself, may be displaced by means of one and the same driving means. The driving chains, as used in the present case, for displacing the front walls and roof-portions, run preferably continuously along the entire length of the hall, whilst the chains which carry the checquered plates for the guide-channel, are divided at the centre (Fig. 8) because these latter chains have to run in contrary directions towards both sides.

I claim i 1. In a building or the like having a pinrality of fixed and movable wall and roofsections; means for displacing the movable Wall sections in a plane parallel with the fixed wall sections; and means for displacing the movable roof section in a plane parallel with the fixed roof sections, whereby the building may be converted into a substantially free open space without dist-urbing its-continuous utilization.

In a building as set-forth in claim 1-, the movable roof and underlying wall sections being rigidly, connected togetherand movable as units and adapted to telescope the fixed roof and underlying wall sections. in combination with a building as set forth in claim 1, said building having fixed ceiling plates mounted below the fixed roof sections, and ceiling plates verticallymovably mounted beneath each movable roof section, and means for raising said movable plates out of engagement with the fixed ceiling plates prior to the displacement of the movable roof sections. I

6. In a building as set forth in claim 1, the moving means for the wall sections being disposed in an open channel at the base of the wall of the building; and means connected with said moving means to automatically cover the open channel when the dis placeable sections are being moved.

In abuilding construction or the like with several stationary and displaceahle wall and roof sections means for displacing the displaceable wall sections with regard to the stationary wall parts; and means for displacing the displaceable roof sections with regard to the stationary roof respectively,
